# Installing Surveys on Headless Instances ## Standard Implementations ### Introduction There are multiple ways to configure and setup headless Connect. There are two main channels it supports: * on-site * post-checkout Both channels support multiple different modes of configuration. Either by passing query string parameters to the script or by creating meta tags inside the page header. ### On Site To display an on site survey, the system chooses from a prioritised list of surveys for the on site channel. From highest priority down, the system choses the first active survey that matches conditions and that the user is eligible for answering.

An example on-site survey list with the priority visible in the numbered boxes.

To implement on site surveys, you can add our surveys script tag to the header of the page(s) with your store Shopify domain. #### Example Usage ```html ``` #### Parameters These query string parameters can be added to the script src.

Parameter	Description	Value Type	Supported Values	Required
`shop`	The store identifier for example `okendo-seahorse-emporium.myshopify.com`	`string`		✅
`channel`	The Okendo Survey channel to load a list of surveys from.	`string`	`on-site`, `post-checkout`	✅
`auto_initialise`	Flag to indicate if the API setup function should be run on page load. Defaults to `false`	`boolean`	`true`, `false`	❌
`customEventsOnly`	Flag to indicate if page event triggers to show surveys should be supressed. Defaults to `false`	`boolean`	`true`, `false`	❌
`targetElementId`	Optional page element id to place the survey inside of.	`string`		❌

### Post Checkout To display a post checkout survey, the system chooses from a prioritised list of surveys for the post checkout channel. From highest priority down, the system choses the first active survey that matches conditions and that the user is eligible for answering. Post-checkout requires extra data needed for the decision making process on which survey to display to a customer. This data is used to determine which post-checkout conditions and triggers match. If only using a simple post checkout survey without conditions you can use the same setup as the above on site section. If you want to use any of the following conditions, you will need to either use the javascript API properties or meta tags as explained below: * Order value is at least * Order value is at most * Purchased product * Cart contents do not include * New Customers * Repeat Customers #### Example Usage ```html

``` #### Parameters The channel parameter needs to be provided as a query string parameter to the script src.

Parameter	Description	Value Type	Supported Values	Required
